I agree depending on nute used I use coco tek a and b bloom and still saw cal mag issues untill I bumped up to 300ppm cal mag but I was growing blue dream which is a known cal mag hog
Cocotek has calcium nitrate in Bloom part A but mostly ammonium nitrate which doesn't really make sense for a product marketed for coco which has higher calcium requirements. But they do sell calmag as well which makes up for the lack of calcium. Which goes back to a previous comment I made about nutrient companies leaving calcium out on purpose so they can sell another product.
